Scientists have caught the first images of a boa constrictor consuming a 9-pound howler monkey, and they are gruesome. In the gallery above, you will see the boa constrictor ingesting the monkey head-first, bit by bit. The images accompany a study describing a play by play of the snake attack published in the journal Primates by Julio Cesar Bicca-Marques of Pontifical Catholic University of Rio Grande do Sul and his student ...

Scientists in Norway have more good news for coffee drinkers. Researchers have already found evidence that the drink -- or the beans it's brewed from -- can help with weight loss , reduce one's risk of developing Alzheimer's disease or dementia, boost muscle growth , protect against certain types of cancers, and can even reduce one's risk of premature death , among many other benefits . Now comes word that a cuppa joe reduces physical...

Screaming at your teenagers to discipline them can make their behavior worse - even if you otherwise have a warm family relationship, researchers say. The effects were comparable to those in studies that focused on physical punishments, the researchers said. “From that we can infer that these results will last the same way that the effects of physical discipline do,” the lead researcher, Ming-Te Wang, an assistant professor of psychology in education at the University of Pittsburgh, said in a statement.

Scientists have infused "life" into inanimate chemical compounds by flashing a blue-violet light that prompted them to assemble themselves into a crystal. The feat, described in a study published online Thursday by the journal Science, marks an important step toward creating "active" materials that can repair themselves, such as a smartphone screen that fixes its own cracks or a Kevlar vest that fills a hole made by a bullet, experts said. Showing that microscopic particles can be made to come together or break apart on their own "opens a new area for design and production of novel and moving structures," wrote the study authors, a team of physicists and chemists from New York University and Brandeis University in Waltham, Mass.

The dark dust thrown up by human activity in the deserts of the Southwest hastens the melting of Rocky Mountain snow and ultimately reduces the amount of water flowing into the upper Colorado River by about 5%, scientists reported Monday. The lost water amounts to more than 250 billion gallons — enough to supply the Los Angeles region for 18 months, said study leader Thomas H. Painter, a snow hydrologist at the Jet Propulsion Laboratory in La Cañada Flintridge. "That's a lot of water," said Painter, whose study was published online by the Proceedings of the National Academy of Sciences.

WASHINGTON -- The Smithsonian National Zoo announced Thursday that the giant panda cub born there two weeks ago is a girl, is very chatty and "has a fat little belly. " Scientists confirmed the sex of the cub, which was born to Mei Xiang (pronounced may-SHONG) on Aug. 23, according to a news release. DNA tests also showed that the zoo's panda Tian Tian (t-YEN t-YEN) is the father of the cub. Mei Xiang was artificially inseminated twice in late March, with sperm from Tian Tian and from a panda named Gao Gao at the San Diego Zoo, after unsuccessful natural breeding attempts with Tian Tian.

A group of scientists warned Tuesday that world leaders must act more swiftly to slow greenhouse gas emissions or risk "abrupt, unpredictable and potentially irreversible changes" from climate change. The American Assn. for the Advancement of Science's blunt report contains no new scientific conclusions. But by speaking in plain, accessible terms it seeks to instill greater urgency in leaders and influence everyday Americans. Scientists said many previous assessments have been long and ponderous, and have failed to shift public opinion on global warming.

In August, NASA's Mars Science Laboratory will reach the Red Planet and begin its search for habitats that could have supported life. The next-generation rover, better known by the nickname Curiosity, will pick its way up a mound in the middle of Gale crater and look for evidence that water once flowed on the Martian surface - a condition that is considered a prerequisite for hosting microbial beings. On an expedition to the California desert this month to demonstrate some of the challenges Curiosity will face on Mars, scientists chatted about the upcoming mission.

Is 2012 the end of the world? If you scan the Internet or believe the marketing campaign behind the movie "2012," scheduled for release in November, you might be forgiven for thinking so. Dozens of books and fake science websites are prophesying the arrival of doomsday that year, by means of a rogue planet colliding with the Earth or some other cataclysmic event. Normally, scientists regard Internet hysteria with nothing more than a raised eyebrow and a shake of the head. But a few scientists have become so concerned at the level of fear they are seeing that they decided not to remain on the sidelines this time.

A team of storm-chasing scientists sampling rarefied air has found a world of bacteria and fungi floating about 30,000 feet above Earth. The findings, detailed Monday in the Proceedings of the National Academy of Sciences, suggest that microbes have the potential to affect the weather. Scientists have long studied airborne bacteria, but they typically do so from the ground, often trekking to mountain peaks to examine microbes in fresh snow. Beyond that, they don't know much about the number and diversity of floating microbes, said study coauthor Athanasios Nenes, an atmospheric scientist at Georgia Tech.
